Hello! I have a backup and I’m trying to restore site with wordpress plugin (all in one migration) but encounter error and import doesn’t finish. And i see in console error 504 gateway timeout . And import doesn’t finish. Import file is small only 100Mb. It starts the proces but during database restoration hangs

I have backup file done with the plugin that is included with your standard installation and I can’t open it with winrar to extract anything and then upload by ftp.
It’s only one file with .wpress that uploads successfully and starts the process but after two minutes of import at 40-50% hangs with error 504 gateway timeout.
